Stem cells are specialized cells in multicellular organisms which are capable of differentiating into a wide variety of cells as needed.
In other words, the very specialized cells, such as blood cells, nerve cells, and so on, but they can make specialized cells to form an embryo or repair damage to an adult organism.
This property has been suggested that stem cells could be useful in treating physician, and many nations have established funds stem cells to explore the possibility of research and development with stem cells.
All multicellular organisms actually begin as a group of stem cells. As cells divide and multiply, differentiate to the organs, muscles, bones, and so on until an embryo is formed. Adults also have stem cells, although its exact origin is not known. These adult stem cells function in response to a serious injury to replace damaged tissues.
There are three types of stem cells. Embryonic stem cells are taken from an embryo stem cells, the stem cells come from the umbilical cord is rich in stem cells, as it is of fetal origin. Adult stem cells are also known as somatic stem cells, and are found in a variety of places around the body of an adult. Exact science and distribution of adult stem cells remains a subject of intense research.
In order to be considered a stem cell must possess two properties. The first is that the cell should not be specialized for a specific operation, but must be able to generate specialized cell types. In addition, stem cells may replicate many times buggy, a process known as proliferation.
The stem cell research focuses on the exploration of these unique properties, and scientists hope to someday be able to exploit stem cells, stimulating them to grow organs for people who need them.
Research on stem cells is controversial in some parts of the world. Embryonic stem cells could be harvested only by adopting an embryo until 2006, when scientists began to prove that stem cell lines could be created without sacrificing an embryo.
Because some people are uncomfortable with the idea of killing an embryo, this issue is of major concern in many communities. Other critics worry that stem cell research may invade the field of cloning, and many communities oppose the cloning of human beings, for a number of reasons.
Most governments have focused on creating a clear and understandable legislation on stem cell research, hoping to harness the immense potential of stem cells without causing controversy.
